What to Expect – Home Underground Utility Locating

Our analyst performing underground utility locating services

When you started your home project, you didn’t imagine that you would need our private underground utility locating services. To ensure that you don’t hit any utility lines, it is important to scan the area first. Damaging utility lines can result in loss of that particular utility. It can also cause injuries for you or the workers hired to do the cutting, trenching, or digging.

For home owners, utility locating can be a first and only experience. This means that it can be hard to know exactly how to proceed. The first step would be to contact 811“call before you dig”, the nationwide public utility locating service. They can locate all public utility lines, from the street to the meter only. If they can’t locate what you need, that’s when we, a private utility locator, come in.

When you call Penhall Technologies or request to quote, it is best to be prepared with essential information regarding the project. This will allow us to provide the best service and accurate pricing. It is important to know the measurements of the area, the type of surface (dirt, asphalt, concrete), and the location (indoors or outdoors). If possible, provide the utilities we may be looking for (water, gas, electrical, sewer) and how many utilities may be running through the area. We will also ask how many locations you need scanned, and what is the private line locating in preparation for.

Example of utility markings at a home


Once the analyst arrives at your home, they will be up to date with the needs and specifications of your project. They will bring two types of equipment to offer you the most accurate reading. A benefit of choosing Penhall Technologies as your private utility locator is that we carry various types of equipment. This is in case one method is not enough to find underground lines. In rare cases, the reading can be inconclusive and show highly congested results.

After the analyst completes the scan, he/she will mark the approximate utility locations with varying colors of spray paint, flags, or both to highlight that location. You can find out what each color means for utility marking in our guide here.

Equipment screen showing utility locating data

Before the analyst marks the utilities, the display screen of the equipment won’t mean much to the common eye. Our expert analysts will be able to identify lines and to differentiate between them based on the data and on physical cues, such as a meter. Now with the analyst’s markings and field report, you can make an informed decision of where to cut, trench, or dig. By deciding to scan first, you will safeguard that your home project is completed safely.
